For all its willingness to serve the viewer generous dollops of violence, noise, and terror, The Purge is oddly lacking in energy.

... though the film struggles to flesh out this rather Dystopian concept (something nearly every futuristic film has these days), it succeeds in its gripping suspense and romantic eye for violence.

An entertaining and deeply unsettling premonition of the state the US's obsession with guns may leave it in.

The big thing with this film is the same thing with every film in this genre; it's extremely predictable and the characters do things they would never do in real life.
